Pontifex - from latin Pontifex Maximus, translated as The Greatest Pontiff. Pontiff means bridge-builder and was used literally as well, but mostly known as the name for the highest clergy, a bridge between Divine and Mortal. Pontiff is one of the titles of the Pope. Could be used as another name for Hierophant, or a High Priest, fitting 8-letter convention.

There is no path.
Beyond the scope of light, beyond the reach of Dark.
What could possibly await us?
And yet, we seek it, insatiably
Such is our fate.
